SPECIFICATION forming part of Iletters Patent No. 672,817, dated April23, 1901. Application fusa January 5, 1901. serai No. 42,193. (Nomodel.)

To a/ZZ whom it may con/cern:

Be it known that we, ARTHUR HENRY BEN- NETT, residing at 44 Swan street,Richmond, and STEPHEN JONES, residing at 51 Athol street, Moonee Ponds,in the Colony of Victoria, subjects of the Queen of Great Britain, haveinvented a new and useful Improvement in Gas-Burners, of which thefollowing is a specification.

Our invention relates to a gas-burner in which a pilot-light is used forlighting the main burner, said pilotlight being extinguished as soon assaid main burner is lighted and again lightedwhen the main burner is eX-tinguished.

We will now describe the invention, having reference to the accompanyingsheet of drawings, in which- Figure 1 shows a view of a small example ofour system of lighting, in which is illustrated a chandelier and awall-bracket. Fig. 2 shows a vertical section of the means forcontrolling the gas-supply to the pilot-light and the burner. Fig. 3shows an elevation of the construction shown in Fig. 2, drawn to asmaller scale, the sanne being here applied to an ordinary gas fittingand burner.

` t ofFig.2.

Fig. 4 shows an edge view of a portion of the parts shown in Fig. 2.Fig. 5 shows a plan of the ball-valve 11 shown on Fig. 2. Fig. 6 shows asection taken on the line A A of Fig. 2. Fig. 7 shows a section taken onthe line B B Fig. 8 illustrates the operating-tap and its adjustableby-pass.

In the drawings, 1, Fig. l1, represents the ordinary gas-supply pipe,and 2 a cock on same. This cock (see Fig. 8) has a by-pass pipe 3, oneend of which enters-the bore of the cock and the other end enters a`cylindrical box 4, the said box being screwed into the bore of the cockon the side of the valve opposite to that which receives the by-passpipeend. The box 4 has a smallindependenttap preferably constructed, asshown, in the form of an adjustable screw 5, which is arranged tocontrol the passage of the bypass 3 and which will normally be kept'openor partly open, so as to allow of a constant passage of gasindependently of the cock 2, so as to supply at all times thepilot-lights, as hereinafter described. The gas-supply to the burner orburners is controlled by the cock 2. Fig. 1 illustrates twoincandescentmantle burners supported by a chandelier 6 and an ordinaryburner on a wall-bracket fitting 7. We employ the following constructionto be connected to the gas-fitting in every case: A cylinder 8 (see Fig.2) is internally threaded at its base 9, so as to screw onto thegas-fitting. This cylinder has a milled rim 19, and the portion abovesame is screwthreaded. The top of this cylinder is beveled at l0, and soforms a seat for au aluminium ball-valve 1l. Said ball-valve has a rod12 attached, and a perforated and open plate 13 is set within thecylinder and forms a guide for the said rod 12 and allows also of apassage of gas. A shouldered tube 1-4 screws onto the top of thecylinder 8 and rests on washer 20, and the shoulder 15 of the tube 14forms a stop for the said valve. The top of. the ball 11 is cut away orgrooved out at 33, Fig. 5, so as to allow of the upward passage of gaswhen the said ball comes against the shoulder 15. The ball will,however, in practice iioat in the tube by reason of the gaspressure whenthe gas-supply cock is turned on. The neck 16 of the shouldered tube isthreaded both internally and externally, so that when the apparatus isemployed in conjunction with a Welsbach gas-burner such burner willscrew onto the external thread; but when employed in conjunction. withan ordinary gas-burner such burner will be received by the internalthread, as shown in Fig. 3. The cylinder 8 is provided at its base witha disk of wire-gauze 18 for the dual purpose of checking any foreignmatters or dust and preventing back-lighting. This cylinder has aperforation through its wall, and a short branch pipe 2l screws intosame. This pipe is preferably set at right angles to the cylinder. Thetop of this branch pipe near its end has a short pipe-section 22 screwedinto it, and the bore of which latter is at right angles to andcommunicates with the bore of branch pipe 21, and the top of thepipe-section forms a seat for an aluminium valve 28. This valve has itstop tapered conically. The wall of this short pipe-section 22 has aperforation 24 through it, and a pipe or tube 25 screws onto the saidpipe-section. The perforation in the wall of the pipe-section 22communicates with a perforation 26 in the pipe or tube 25 near its base,and which latter communicates with a by-passage 27,V

formed by a casing 28 on the tube 25, and

`which has an opening 29 into the said pipe -same being designed tocontrol the opening 24, so as to regulate the amount of flow of gas tosupply the pilot-light.

34 represents the pilot tube, which is screwed into top of the pipe 25.We provide an adjusting-screw 32, which screws into the bottom of thebranch pipe 2l and has a tapered point which is arranged to regulate theamount of opening of the pipe-section 22, the object of this screw beingto control the gaspressure entering the said pipe-section.

37, Fig. 3, represents an` ordinary gas-fitting in which the cylinder 8is mounted, and17 a burner on the tube 14. When the apparatus .isemployed in conjunction with an ordinary gas-burner, the pilot-tube maybe bent to meet the burner, as indicated in Fig. 3; but when theapparatus is employed in conjunction with an incandescent-mantle burnerthe end of tube 34 will be received by a tube 35, which latter enters oris attached to the burner, as indicated at 36, Fig. 1, or otherwise.

The valves are constructed of aluminium,

' same being a light and serviceable metal; but

other suitable metal or material may be substituted therefor, providedthat the loatability of the valves is preserved.

The modus'opemndt' of our invention is as follows: Assuming the cock 2on the supplypipe 1 to be turned on and the adjusting' screw 5 set toregulate the required flow of gas to supply the pilot-lightindependently of the cock 2, the gas will pass by the main pipe and it-sbranches to the gas-iittings and through same to the cylinder. 8,mounted thereon, and its pressure will cause the aluminium ball-valve l1(see Fig. 2) to rise from` its seat l0 and allowr the full supply ofgasy to pass to the gas-burner above. The gaspressure will cause thevalve to ioat in the chamber; but should it rise to the shoulder 15 theincisions or grooves 33 in the ball will flat bottom seat and close upagainst the conical seat formed inside the top of the pipe or tube 25,in which it is set, so closing up' the gas-passage to the pilot-lighttube 34. Ou turning oi the supply-cock 2 the valves 11 and 23 will bothfall onto their bottom seats, and the gas which escapes by the by-` pass3, `Fig. 8, and passes along the supplypipe being at very low pressurewill not have suiiicient force to raise the valves, and thislow-*pressure gas will pass from cylinder 8 through the branch pipe 21to the regulated mouth of and through the pipe-section 22 and throughthe regulated hole 24 in the wall of same to the by-passage 27, thencethrough the opening 29 into the pipe or tube 25above the valve, (whichlatter, as before described, will be resting upon the top of thepipe-section,) and thence to the pilot-tube 34. This action will takeplace sufficiently quickly to cause the pilot to light before the mainlight becomes quite extinguished. The actions above described will berepeated on each turning on and off of the main cock, and it will beunderstood that the pilot-lightwill always be kept going while the mainlight or lights is or are out.

Referring to the pipe 34, we would have it understood that such duct maybe modified or altered' in its construction or dimensions With regard tothe aluminium being used as the material vfrom which to construct thevalves 11 and. 23 we would say that we have found such metal to besuitable on account of its lightness and peculiar metallic properties;but we reserve to ourselves the right of constructing such valves of anyother suitable metal or material either in a hollow or solid form.l

It will be understood from the foregoing eX- planations that a largenumber of the gasburners fitted with our parts hereinbefore referred tocan be distributed over a large hall or building, and after being oncelighted the whole of such burners can be turned on or off by onemovement of the hand operating a cock, as 2, at any convenient centeror` room or alternatively at the gas-meter, the portions of the pipe 3and the adjustment of the screwcock 5 being previously suitably set inaccordance with the number of burners-in the system.

It may be noted that where the ordinary gas-taps 38 are used anyindividual light may be shut off if not required. In somewhatsimilarmanner to that above described our system and apparatusmay be applied tothe lighting of street-lamps. In this case the attendant need simplyturn on the one cock at night, and vice Versa in the morning, thusobviating the present extravagant system, wherein each individual burnermust be operated by an employee either before or after the exact propertime for lighting such gas. The use of our invention thus economizes theIOO IIO

gas consumed before the proper minute for lighting at night and the gasconsumed after the proper minute when the light should be extinguishedin the morning.
